Alkali and alkaline earth metal salts of tetrazolone: Structurally interesting and excellently thermostable

Tetrazolone (5-oxotetrazole) was synthesized by a moderate strategy through three steps (addition, cyclization and catalytic hydrogenation) avoiding the unstable intermediate diazonium, as reported during the previous preparation. Alkali and alkaline earth metal salts with lithium (1), sodium (2), potassium (3), rubidium (4) caesium (5), magnesium (6), calcium (7), strontium (8) and barium (9) were prepared and fully characterized using elemental analysis, IR and NMR spectroscopy, DSC and TG analysis. All metal salts were characterized via single-crystal X-ray diffraction. They crystallize in common space groups with high densities ranging from 1.479 (1) to 3.060 g cm-3 (5). Furthermore, the crystal structures of 7, 8 and 9 reveal interesting porous energetic coordination polymers with strong hydrogen bond interactions. All new salts have good thermal stabilities with decomposition temperature between 215.0 °C (4) and 328.2 °C (7), significantly higher than that of the reported nitrogen-rich salt neutral tetrazolone. The sensitivities towards impact and friction were tested using standard methods, and all the tetrazolone-based compounds investigated can be classified into insensitive. The flame test of these metal salts supports their potential use as perchlorate-free pyrotechnics or eco-friendly insensitive energetic materials.

One-pot synthesis of carbamoyl azides directly from primary alcohols and oxidation of secondary alcohols to ketones using iodobenzene dichloride in combination with sodium azide

An effective synthesis of carbamoyl azides directly from primary alcohols using iodobenzene dichloride in combination with sodium azide has been developed. Moreover, the same regent combination was also efficient for the oxidation of secondary alcohols to the corresponding ketones.

Synthesis of carbamoyl azides from primary amines and carbon dioxide under mild conditions

(Chemical Equation Presented) Treatment of amines under a carbon dioxide atmosphere with tetramethylphenylguanidine (PhTMG) and diphenylphosphoryl azide (DPPA) in acetonitrile below 0°C provides carbamoyl azides in high to excellent yields. In addition, e

One-flask conversion of carboxylic acids into carbamoyl azides

Carbamoyl azides can be generated in high yields from the corresponding carboxylic acid and triphenylphosphine by adding NCS, followed by sodium azide and triethylamine hydrochloride.

One-step Conversion of Esters to Acyl Azides Using Diethylaluminum Azide

Diethylaluminum azide, prepared from either sodium azide and diethylaluminum chloride or hydrazoic acid and triethylaluminum, reacts with esters to yield acyl azides in one step.
